Etymology: "Gleefulest" is the superlative of "gleeful," formed by adding the suffix "-est" to that adjective. Note that the form is more often written with "most" ("most gleeful") in modern English, and "-est" superlatives on longer or less common adjectives are considered somewhat unusual, though they are used in writing and speech. "Gleeful" is formed from "glee" plus the suffix "-ful," meaning "full of." "Glee" comes from Old English "gleo," meaning music, entertainment, or merriment, a sense that survived in the word's connection to musical performance. The original meaning was closer to revelry or minstrelsy than to a private feeling of happiness, and the emotional sense developed later.
